+= Override kernel version check 
+
+The `-no-kernel-version-check` flag, or the `no-kernel-version-check` key in the host-agent configuration file, controls the kernel version compatibility check during the profiling host-agent's startup process. The kernel version compatibility check enforces the minimum kernel version supported,  and prevents the profiling agent from running on certain kernel versions with known issues. When the `no-kernel-version-check` is set to `true`, the compatibility check is bypassed, allowing host-agent execution to proceed regardless of the kernel version. By default, this option is set to `false`, and the kernel compatibility version check is performed as usual.
+
+WARNING: Take extra caution when using this configuration option, especially when running the host-agent on older kernels with backported eBPF functionalities. Setting this option to `true` on kernels with unfixed eBPF bugs can crash your system.

+== Host agent configuration example
+
+The following example shows how to configure the `-no-kernel-version-check` in the Universal Profiling agent CLI:
+
+[source,bash]
+----
+sudo pf-host-agent/pf-host-agent -no-kernel-version-check=true ...'
+----
